Valley Passive House in Minnesota Revisited Post-Construction

About a year ago, Rise’s founder Matt Daigle had a chat with Jennifer and D.R. Schroeder about the Passive House they were building in Minnesota. “Early in our relationship, we discovered that a shared value was living sustainability and responsibility,” said Jennifer.

“Some of that’s easy: composting, recycling, knowing where your food comes from, where your clothes come from,” she continued. The Schroeders wanted, however, to go beyond those approaches. They wanted to discover how to live with a lighter footprint on their lakeside property while contributing in a positive way to their neighborhood and the world at large.

The solution was building a new home to Passive House standards, without sacrificing the modern aesthetic that they love. They had their architect, Dave Zweber, principal, David Charlez Designs, in Lakeville, design the home of their dreams. Then, says D.R., “We had our builder make it a Passive House.” A Certified Passive House consultant, Ryan Stegora, owner of RJ Stegora Inc., brought to the project history of building highly energy efficient and durable buildings.

“We don’t feel like we had to sacrifice on either end,” said Jennifer of the modern design and the Passive House construction. The Schroeders and their children moved into their new home in May 2019.

Developed in Germany, Passive House design includes five basic principles. Continuous insulation throughout the entire shell is the first principle. The second is airtightness, to stop heat loss and moisture accumulation. The third is installing energy-efficient windows that bring in solar heat during the cold months. Balancing ventilation for constant fresh air is the fourth. As a result (principle number five), the home requires minimal, if any, heating and cooling using mechanical systems.

The Schroeders’ home boasts triple-pane windows and a flat-roof assembly that’s 23-inches thick. The highly insulated walls are approximately 19 inches thick. The all-electric home has a heat pump hot-water heat, heat pump dryer, Energy Star appliances, and an induction cooktop: A rooftop solar array powers them all. The home has all LED lighting, used no- or low-VOC paint, incorporated FSC-certified wood, and has low-flow plumbing fixtures and toilets.

The builder constructed the home’s deck of black locust wood, which is considered an environmentally friendly alternative to ipe. (A rare and overharvested wood from Central and South America, ipe grows in low densities: Mature trees appear once every 300,000 to 1,000,000 square feet. Harvesters cut through the rainforest to reach those mature trees, resulting in deforestation and waste.) Around the deck, the Schroeders planted a low- to no-mow pollinator-friendly lawn, and drought-resistant native plants.

We asked D. R. Schroeder to how the family likes living in their new modern Passive House, and advice they have for other homeowners wanting to build sustainability.

Thick Coat Versus Light Jacket

Rise: Talk more about why you wanted to build a sustainable home using Passive House principles. What about Passive House strategies made sense to you? What other sustainable strategies did you incorporate?

D.R.: Our dream of building a sustainable home originated because of a shared belief in climate change. In learning about climate change, we discovered how building practices impact the environment. From there, we did further research about sustainable techniques. Eventually, we learned about Passive House, which makes so much sense, as far as addressing the energy consumption issue at the root of climate change.

Building a sustainable, energy-efficient home was reaffirmed on both short-term and long-term levels when we had children. One of our children has allergies, making the healthy home environment we were learning about in our sustainability research quite appealing. Long term, we hope that building an energy-efficient home can help shift the conversation in the building industry toward making energy efficiency a mainstream idea.

Rely on the Fundamentals

Rise: What was the most valuable research you found? What research would you point other homeowners to when seeking to build a Passive House or sustainable home?

D.R.: One of the most valuable things we learned is that, at a basic level, sustainability relies on simple fundamentals: A well-insulated building envelope that minimizes thermal bridging and air leakage, combined with balanced ventilation add up to low energy usage. In other words, you can build a home well, and it will require a lot less energy to heat and cool. Sustainable energy solutions are great; the better solution is not needing so much power in the first place. As we live in Minnesota, a great analogy is thinking of a Passive House as a nice, thick winter coat. Traditional building results in “light jackets” that require a steady stream of hand warmers in the pockets.

Rise: How did you adapt Passive House principles, which were developed in Germany, to address the Minnesota climate?

D.R.: Constructing a Passive House in Minnesota isn’t impossible. Passive House Institute US (PHIUS) has standards for different climate zones. Our builder was able to use PHIUS’s modeling to analyze and prescribe the right solutions for our project in a challenging climate. Our home has a lot of insulation!

Modern Design, Passive House Performance

Rise: What do you love most about living in the house?

D.R.: Our favorite thing about the home is that we were able to get a design we love while still getting extreme energy efficiency and performance. We sought out our architect because we loved his style (he had no previous Passive House experience), and he delivered a wonderful design. Our builder was then able to modify that design into a home that reaches Passive House standards. We couldn’t be happier with the result. It’s the home we dreamed of, and the performance is certainly there. Blower-door testing of airtightness yielded an ACH of 0.15 based on a measured 130 cfm @ 50 pascals (for reference, Passivhaus standard is 0.60 ACH and new homes in Minnesota around 2.5 ACH).

We’ve been in the house for a few months now. We’re happy with how well the home has maintained an indoor temperature and how quiet it has been. Over the summer, we received monthly checks back from our utility as part of its net metering program. Having your utility company pay you is quite the contrast! Outside of its performance, we love the home’s floating staircase and the screened porch.

Making Passive House Mainstream

Rise: What advice would you give to other potential homeowners who wish to build a house to Passive House standards? What do they need to consider? What are the pros and cons?

D.R.: We learned a lot along the way in our project. Probably the most important was finding a good builder who is motivated to adopt a non-mainstream technique like Passive House. Your builder is going to be the one dealing with the day-to-day implementation of the design. You need a builder who is on board with delivering a project that isn’t like most homes, as far as building technique. Building a Passive House takes a team of people. Our advice is to start that team with the home builder or contractor.

If you are considering building a new home, we encourage you to explore Passive House. There are some additional up-front costs to upgrade building materials like high-performance windows, but the long-term benefits of less energy use and a comfortable home are worth it. As homeowners create more demand for energy-efficient, high-performance homes, the building industry will respond and help shift improved energy efficiency into the mainstream.
